What are persisted queries?

A persisted query is a query string that's cached on the server side, along with its unique identifier (always its SHA-256 hash). Clients can send this identifier instead of the corresponding query string, thus reducing request sizes dramatically (response sizes are unaffected).

How do I save a query in Apollo GraphQL?

Saving an operation

Click on the save icon in the editor pane, left of the run button. You can also use the keyboard shortcut of Cmd/Ctrl+S . Give the operation a name, select the collection to save in, and hit Save! Your operation is now saved and available for access within that collection 🎊

Can I use Apollo Client with REST API?

You can use apollo-link-rest to call REST API inside your GraphQL queries.

What are active queries Apollo?

When you see “active query”, it's referring to your second option: any query that's part of a rendered component, regardless of whether the query is currently executing.

How do you make a computed column persisted?

Creating a Persisted Computed Column

To qualify for persistence, the column must be deterministic; that is, the expression must always return the same results when given the same input. For example, you cannot use the GETDATE function in the column's expression because the returned value is always changing.

How do you check if computed column is persisted?

Note that a computed column is persisted only if its expression is deterministic. It means that for a set of inputs, the expression always returns the same result. For example, the expression first_name + ' ' + last_name is deterministic.

Are GraphQL queries always post?

The GraphQL spec is itself transport-agnostic, however the convention adopted by the community has been to utilize POST requests. As pointed out in the comments, some libraries support GET requests. However, when doing so, the query has to be sent as a URL query parameter since GET requests can't have bodies.

Are GraphQL queries get or post?

GraphQL requests can be sent via HTTP POST or HTTP GET requests. GET requests must be sent in the following format. The query, variables, and operation are sent as URL-encoded query parameters in the URL. In either request method (POST or GET), only query is required.

Is REST API better than GraphQL?

GraphQL community is growing and Rest are Large. GraphQL performance is fast and Rest are multiple network calls take up more time. GraphQL development speed is rapid and Rest are slower. GraphQL learning curve is difficult and Rest are moderate.

Why GraphQL is not a REST API?

GraphQL simplifies the task of aggregating data from multiple sources or APIs and then resolving the data to the client in a single API call. On the other hand, API technologies like REST would require multiple HTTP calls to access data from multiple sources.

Should I use GraphQL instead of REST?

REST doesn't give you those affordances. If optimizing for network requests is the most important factor, GraphQL would work better for you. With GraphQL, you'll get only the information you need. This is due to a self-documenting schema that's easier to consume and has better tooling around consuming your endpoint.

What is persist for in looker?

persist_for lets you modify the amount of time that cached query results are used for a given Explore. The default cache length in Looker is 1 hour. Cache results are stored in an encrypted file on your Looker instance.

What are queries in Logseq?

Queries are a powerful tool to search your Logseq graph. Under the hood, Logseq uses Datascript for the database and Datalog as the query engine. The built-in queries of Logseq are all written in Datalog, and you can write your own using the language.

Is persist better than cache?

The only difference between cache() and persist() is ,using Cache technique we can save intermediate results in memory only when needed while in Persist() we can save the intermediate results in 5 storage levels(MEMORY_ONLY, MEMORY_AND_DISK, MEMORY_ONLY_SER, MEMORY_AND_DISK_SER, DISK_ONLY).

Why do we persist data?

Persistence is important in programming because it means that data that is persisted to storage that can be accessed from different applications, different devices, and different operating systems.

How do you persist data?

Enabling data persistence on data variables

From Application Designer, switch Variables tab for your application. Select a data variable from your list. If the list is empty, create a data variable that you want to persist. For the Persist data to value, set to User or Application.

What are the 4 types of queries?

They are: Select queries • Action queries • Parameter queries • Crosstab queries • SQL queries.

What are the two types of queries?

Two types of queries are available, snapshot queries and continuous queries.
